järjestämiinsä

järjestämiinsä is a Finnish word. It is the genitive plural form of the past passive participle of the verb järjestää, which means to arrange, organize, or host. Therefore, järjestämiinsä literally translates to "those that have been arranged by them" or "those that they have arranged."

In practice, the word is used to refer to events, actions, or items that a specific group of people has organized or arranged. The context of the sentence will determine the precise meaning. For example, "hänen järjestämiinsä juhliin" would mean "to the parties that he/she has arranged." The suffix "-nsä" indicates possession or relation to a third person, plural or singular. Thus, järjestämiinsä signifies something arranged by "them" or "his/her/its/their own."

The word's structure reflects Finnish grammar, which is agglutinative. This means that suffixes are added to a base word to convey grammatical information. Järjestää is the verb stem. The past passive participle is formed from this stem. Then, the plural and genitive case are indicated by further suffixes, culminating in järjestämiinsä.
